I updated my bios to v1.16 but when the it was done installing it shutted down and now when i turn my laptop on the screen is all black, i know i have to reflash the bios but i have no idea how to do this, could someone please help me?

if you have different suggestions for what could fix this problem, im willing to try anything to fix it..

You will have to unplug all power and remove the battery from the laptop
then you have to open the laptop and remove the motherboard CMOS battery and leave it out for atleast few minutes and that should reset the BIOS

why did you updated the BIOS version? was it to fix some problem

Its impossible for me to do that since the CMOS battery is so far hidden in the casing, i can only get to the hard drive and the ddr3 ram slots, I have no idea how to get to the CMOS battery in this laptop

i updated the bios version to fix the battery issue (battery cells died because i didnt install the critical battery 3 to 5% update

The CMOS needs to be reset to bring the laptop back to life. Perhaps you have a friend that can do it? "Some" laptops have a pair of CMOS solder joints that can be shorted to rest the CMOS. The owner's manual should have the required info.

Oh.. i thought i had to reflash the bios, which im not able to do myself since i dont have an external usb floppy drive, did not know i really had to crack open the whole laptop, actually i AM the friend who usually does stuff like that xP I just got a pretty closed built laptop so its kinda difficult

GENTLY touch both pins, at the same time, with a small metal object (i.e. small flat blade screwdriver).

I got a new problem.. i couldnt find the J1 jumpers so i took out the cmos battery, when i putted my laptop back together and putted in the AC, it automatically switched on, the fan went on, for a few seconds, and then i still got black screen, what could have gone wrong?
